Note:—In the protologue, Handel-Mazzetti (1933) provided the following locality information when describing Rubus hemithyrsus : “W-Yünnan:Auf und zwischen Sträuchern in Gebüschen der Nmaika-salwin-Kette, 26°40’, 2750- 3000 m, VIII. 1919 (Forrest 18348)”.We located 4 duplicate specimens, which have been deposited in A (barcode 00040608), E (barcode 00010601), K (barcode 000737847), and W (barcode 0131823). All these collections should be regarded as syntypes (Art. 9.6 of ICN). However, the specimen of “ Forrest 18348 ” in A and K, cannot be select as lectotype, because the sheet bear the dated “1917”, but in the original protologue cited the dated “ VIII. 1919 ”. According to Stafleu and Cowan (1979), Handel-Mazzetti’ original type material was deposited in W and WU. We located original material at W and E, both of them matching the locality and date mentioned above. We designate the blooming specimen of “ Forrest 18348 ” at W (barcode 0131823), where Handel-Mazzetti worked as the lectotype, since it is morphological complete with the presence of stem, leaves, and flowers that fully correspond with the protologue.
